My present inyention has reference to an 7 air engine and has for toproduce a construction whereby outs e alrand drait created therefrom are utilized for nnpart- A furthertob'eet is the provision of an air engine in w ich outside currents of a r are caused to contact with and rotate a pro pellerflhaving Vertically disposed radial blades and to be directed therefrom onto the blades of a propeller of the hel cal type and from thence direetedinto-ea stack 1n whichthene is arranged an axial'fiow propeller designed to be actuated by the cur rents of air created by the draft through the stack, all of :the propellers being sew cured upon a suitable shaft which 1s,;-of course, rotated with the propelTers end which is designed to impart motion to a power shaft. a

A further object is the pro-vislo'n of an air engine in which both outside air and currents ofairdirectedth-rough a stack are utilized for imparting a continuous rnove ment to a" shaft, and in which n ean is provided for directing the] outside air against one of the propellers, means regulnt'ing the amount of air contacting such propeller, and means being also. provided for regulating the speed of the shatt operated by the propellers; v 1,5 ,v H T the ettainmentflof the above broadly stated objects and others which will appeer the nature of the invention is better understood; the improvement further re sides in the novel construction, operative assoeiationend arrangement of parts such as is, d sc osed by't'he drawings. which 21 9 company and which form of th s apply cation and pointed out with, particular ty in the append dcleimsg In the draWingsf- Figure 1 isle side eleyation of my iniprbnement, :with parts'flin secti n.

Figure 5 is a fragmentary sectional View substantially similar to 'Figuret but illus trating aslight modification, i "As disclosed by the drawings, 1 inake use of a'suitable base On this base I secure a skeleton frame, the same comprising any desired number of "spaced uprights V2, On thelfr'anie uprights 2, at the outer portions thereof I secure the depending skirt portion {5 of a dome 4. The doin'e round in plan and has a fiat top, provided with a opening thatissurrounded by an outstandingstack 5; v0n the basel there is centrally secured a bearing c rer one o-flth'e conical central ends ofayertically dis oofsed shaft 7. The

second or upperend of t e s haftis journaled in a conical recess in the end of an ustable bearing '8, the saidbearing being preferably in the nature of a threaded element which is screwed through a brace 9 yerselyiin the stack 5, a O the shat 5' nbovethe bearing 6 there is fixed a gearwheel '10 that is in mesh with a;

pinion 11 on one end of adriyen shaft 12.

The shaft 12 is journaled in suitable bearings 13 supported from the base lyand has .onits outereud a pulley 14 for an endlesslbeltthat is designed to be connected to a; suitable machine to be driven. The turning of the shaft 121s regulated by hand ioperated brake mechanism broadly indicated by the numenus, v i

Above the gear 1.0 vthere i fixed 0n the shaft 7 .a :fiy Wheel 16 and abone the fly Wheel .therelis fixed on thesaid shaft 7 the hollow central portion or core 17 of two. rope'l'lers'} The lower propeller has spaced radial blades 18 the planes Of-Which are verti cafl, These'blndes, are secured to the 00118 1:7 and thesebledes may be concave-convex in cros se t on, as illustrated inFigure 01' the same may be .straight,- as disclosed Figure 5 The straight blades, indicated for distinction by, the numeral 18, are arranged at Outward angles which are differently pitched so ,as to. provide a flared 11110113011- for the pocketsfmprovided ,bGtWBQILGEtCh pair Qt -blades. This arrangement is also true with respect to the cross? sectionally rounded blades 18; thatis theiinner ends thereof are farranged trans disposed closer to the tubular core 17 than are the outer ends thereof. In each instance, the lower ends of the blades are secured upon a flange 20 that extends a suitable distance from the sides of the core 17.

The deflector propeller is of a helical type and is broadly indicated by the numeral 20 and is, as previously intimated, formed" on the top of the radial propeller, The

blades 21 of the helical type"propeller'are' extendedfrom ;the core 17 in the same direction but at slightly different angles whereby the lower edges of the adjacent blades 21' are spaced away from each other a greater distance than are the upper ed'ges of the said blades; Also the blades of the deflector propeller 20 are disposed over the pockets, proided between the blades of'the radial propeller so that the Currents of air received between the blades of theradial propellerwill be directed-between each-,pairof blades of the deflector propelle'rto "further assist in the simultaneous turning of both propellers byYthe'currents of air thereagainst.

Secured on the shaft 7 at the portion thereof received within thestack' 5 there is an axia'l'rflow propeller 22. \Thebladesof this propeller rot-ateangularly from the hub thereof and the suction created by the air in its passage through the stack, which is accelerated by the'outsidecurrents of air above the stack creates a suction which materially adds to the efie'ctiveness of the propeller 22 in"assist'ing the radial and helical type propellers in turning the shaft 7. Thus with my, improvement the shaft. Twill be propelled both bythe influenceof outside air a'nd by air suction created through the stacln The parts constituting the improve-- n1ent,a' s above described, may becheaply constructed and assembled, andthe shaft 7 will continue to operate as long asthere is suflici'ent air or wind to operate the several propellers. The turning of the shaft '12,'as previously stated, may be regulatedby' the means 15, but in addition to this, I arrange a in the stack 5 a valve 23 to regulate, and if desired, to wholly close the air passage through the stack, and in this m'annerlikewise regulate the turning of the shaft 7 v y and consequently theturning of the shaft 12'.

The dome has arranged thereover the crown portion 24: of a casing 25. The casingdoes not fully enclose the skeleton frame, but has its lower edge disposed slightly be-l low the radial propeller. Between the crown,

' "and the dome 4 there are anti-frictional bearings-26 toinsure the free turning of the casing" on the device. The crown p01? tion is provided with a vane 27 designed to befinfluenoed by outside currentsof airtof turn the fca'sing to br1n'g"an;,open1n- 28' therein opposite certain of the blades 0 the radial propeller. The air inlet opening 28f may be closed'by a 'slidabledoor 29 ormay throughthe dome, a radial the shaft, a helical type air de ecting pro f be partly closed so that the flow of air to the radial propeller maybe shut off or may be regulated. In certai-ninstancesthe'casing 25 may be dispensed with, but by its employment, it will be noted that a full yol- .-.'.ume ofair; currents will be directed against The cur- 7 stack as also previously intimated, so will be seen that both outside and inside air cur rents, arecausedto influence the blades or '7 yanes of an or the propellers .so' that 1 a {constant and rapidirotary motion isimparted to the shafts 7 and 12', I It is manifest that view of their' s ize, with respect to the. axial'fi'ow'propellei' 22; and also incident to the fact that the'radial propeller is subjected to the "direct" force "of outside air, the 7 combined radial and helical type propellers exert great amount "of a power in rotating the shaft but'this power is materially accelerated by the suction of the air through the stack and the action of such air on theconiparatively smallhorizontal suction propeller 22. a

The improvement 1s, of'cour'se, susceptible to such changes and modifications "as fairly fall within the scopefof what If olai1n and therefore I am not to be limited to" the structural features herein setforth and dis closed by the drawings. I
